Question

whatis gravitation ? define relation between G and g​

Answer 1

Explanation:

G is a constant throughout space and time. g = 9.8 m/s^2 . g is a variable quantity. G is a scalar quantity whereas g is a vector qualtity. (According to Newton's law of universal gravitation the force of attraction between two bodies is given by F = GMm/r^2, where the symbols stand for their usual well known meaning

Answer 2

Answer:

G stands for Newton's universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point.

G = 6.67300 × 10^(-11) Nm^2/kg^2. G is a constant throughout space and time.

g = 9.8 m/s^2 . g is a variable quantity.

G is a scalar quantity whereas g is a vector qualtity.  

 

(According to Newton's law of universal gravitation the force of attraction between two bodies is given by F = GMm/r^2, where the symbols stand for their usual well known meanings. Also the weight of a body of mass m is F = mg.

So mg = GMm/r^2, or g = GM/r^2

g is a constant at a given location, which depends upon M and r.
